What steps would you do to solve 3x-52 -12?
1. Add-12, then divide by 3
2. Divide by 3, then add 5
3. Multiply by 3, then subtract 5
4. Add 5, then divide by 3

Answer:

95

Step-by-step explanation:

8455/89 is 95

Answer:

10 +c=3

C=3-10

C=-7

.....

Answer:

c = -7

10 more than a number c is 3

the variable is c, according to the sentence.

c

"10 more than a number c"

c + 10

"10 more than a number c is 3 "

c + 10 = 3

now that you have your equation, time to solve it.

it's important to know that if you do something to an equation, as long as you do it to both sides the equation is still true.

for example.

2 + 2 = 4

if you add 1 to both sides of the equation,

2 + 2 + 1 = 4 + 1

5 = 5

this is still true.

c + 10 = 3

subtract 10 from both sides of the equation.

c + 10 - 10 = 3 - 10

c = 3 - 10

c = -7

Answer: -53 then -24 then 0 then 18

Answer:

(7,7)

Step-by-step explanation:

Because going up would be moving along the y-axis, then you would add 5 to the Y value which was 2 so therefore, if you move up 5 you'll be at (7,7).:)

Answer:

(7,7)

Step-by-step explanation:

The second number is the y value so you add five to two and you get seven.

Answer:

b=d/2a -c

Step-by-step explanation:

b+c=d/2a (Divide 2a on both sides to elimnate the 2a on the left side)

b=d/2a -c (Subtract c on both sides to elimnate the c on the left side)

Answer: b=d/2a -c

Answer:

Mean is 12.13 months

Standard deviation is 1.29

Step-by-step explanation:

We need to use z-score here

Let the mean of the distribution be a while the standard deviation be b

Mathematically;

z-score = (x-mean)/SD

We can obtain the probability from the z-score

Now, for the 10th month

The z-score for a probability of P = 0.05(5%)

Can be obtained from the standard normal distribution table and that is;

-1.645

Hence;

-1.645 = (10 - a)/b

-1.645 b = 10 - a

a = 10 + 1.645b ••••••(i)

For the 13 month, we have a proportion of 75%

The z-score corresponding to P(0.75) is = 0.674 from standard normal distribution table

Hence;

0.674 = (13-a)/b

0.674b = 13 - a

a = 13 - 0.674b. •••••(ii)

Now equate both a;

10 + 1.645b = 13 - 0.674b

13-10 = 1.645 b+ 0.674b

3 = 2.319b

b = 3/2.319

b = 1.294

So the mean a will be

10 + 1.645b = 10 + 1.645(1.294) = 10 + 2.13

So mean is 12.13

Answer:

C. Associative Property

Step-by-step explanation:

The associative property of addition states that changing the grouping of the addends does not change the sum.

(-7+3)= -4

-4+9= 5

(3+9)= 12

-7+12=5

75 Percent

Step-by-step explanation:

66/88 = .75, which equates to 75 percent.

Answer:

5)y=2x   6)y=12x    7)y=3x-2    8)y=1/4x+2

Step-by-step explanation:

Look at the y-intercept first if crosses the origin then don't need to write anything. If it does you add it after the slope.

To find slope you can count how many units up or down it does and how many left or right.

Then write i as rise/run.

Answer: If you want me to simplify, the answer is -4y - 7.

Step-by-step explanation: Just add the like terms (-4 and -3) to get -7. Then you have the y, which gives you -4y - 7.

Answer:

If there is more than one X value in the ordered pairs and they have different Y values, it is not a function. Otherwise, it is a functio

Answer:

You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!

Answer:

3/14

Step-by-step explanation:

There are 14 marbles, 5 are yellow, 6 are blue, and 3 are pink. You have a 5/14 chance to get a yellow marble, a 6/14 chance to get a blue marble, and a 3/14 chance to get a pink marble.
